Could you link me to a guide on 1D LUT vs. 3D LUT? It is awfully confusing to me - I need simple terms. I thought that the whole idea of D65 REC. 709 standard was that it was a standard to make all displays look the same so that you can view the image in its original form. I can correct all of my color spaces with software without having to use 3D LUT because everything I have done now was through hardware. What I can't figure out is whether there is a difference between theoretical 100% perfectly accurate calibration using 1D LUT and theoretical 100% perfectly accurate calibration using 3D LUT? A standard is a standard.. or not?
People often mix up the terms 1D and 3D. A gray scale calibration is called 1D because it corrects only one axis of your color space. The CMS controls on your display (hue, sat, lightness) are actually 3D but they contain only 6 control points. These 6 control points usually aren't enough to remove all errors with respect to rec.709 or whatever color space you are aiming for. The madVR 3DLUT(software) and eeColorbox 3DLUT (hardware) contain many thousands of control points that can be used to correct color. The basic process work flow is:
Characterize your display errors (profile) -> calculate what adjustment need to be made to the source to remove errors at the display->Load those adjustments into your 3DLUT device.
